Activity monitor will not let me look at things on only one server

I have 4 SQL servers in my company. I can launch Activity Monitor locally from my desktop and connect to 3 of the 4. When I remote on to the problem server, I am unable to launch Activity Monitor that way, either. Now, I have checked all permissions (local and SQL). Nothing changed, but this started happening just yesterday. Any help would be appreciated.

Issue was with the WMI service - specifically the IP Helper dependent service. It wouldn't allow anyone to connect via Activity monitor. Not sure why IP Helper specifically, but that's what I was able to narrow it down to. Once the server was rebooted, the issue was resolved. Thanks to everyone for their comments.

You need the necessary permissions to connect to the Windows Server which are required for WMI.

Permissions were there yesterday. Still are.
The Lifecycle Approach to Managing Security Policy

Managing application connectivity and security policies can be achieved more effectively when following a framework that automates repeatable processes and ensures that the right activities are performed in the right order.

Sorry to baldly contradict you, but obviously something has changed. Check the WMI on the problem box: check out Microsoft links here and here for info on how to do it. Also google this phrase: "check health of WMI" for more suggestions.
